Introduction

The concept of overview or review constitutes one of the most widely used approaches to scientific literature. Its goal is the collection, organization, and presentation of knowledge in a clear and comprehensive way. Although the use of the term has evolved over time, it remains an important methodological practice for capturing and understanding a subject, especially for those approaching it for the first time.

Definition and Evolution of the Term

An overview or review is defined as a general summary of the literature that seeks to record and present the main features of a scientific field. Initially, the term was used synonymously with the systematic review, which caused confusion regarding its content and methodology. With the development of literature and the need for more typological distinctions, the overview acquired a broader meaning, covering different types of reviews with varying degrees of systematization.

The Usefulness of the Overview

Overviews hold a central place in academic and scientific research. They are tools that allow scholars to gain a comprehensive picture of a topic without the need for in-depth analysis of each individual source. Through the overview, an organized and comprehensive presentation of existing knowledge is provided, gaps in the literature are identified which may serve as the basis for future research, and new researchers are assisted in understanding the background of a field and identifying critical directions.

Overview versus Systematic Review

While the systematic review focuses on detailed, methodical, and predetermined data collection, the overview offers greater flexibility. Its methodology does not necessarily follow strict inclusion or exclusion criteria of studies, thus allowing a more generalized depiction. This feature makes the overview valuable in cases where a quick and broad understanding of a subject is required without losing the essence of the information.

The Role of the Overview in Learning and Research

The overview is not only a summarizing tool but also a learning medium. Through it, the reader develops the ability to understand the key concepts and trends of a field, while the researcher can determine the context within which to place their own contribution. At the same time, the comparative analysis of different studies and theoretical approaches is facilitated. Overviews also help to avoid duplication in research, since they present what has already been studied and with what results, thereby enhancing originality and targeted knowledge production.

Challenges and Limitations

Despite their usefulness, overviews also present certain limitations. The most important relates to the degree of systematization. Because they do not always follow strict methodological frameworks, there is a risk of bias or incomplete coverage of the subject. Moreover, excessive generalization can lead to the loss of significant details that would have been identified in a systematic review.

The overview or review represents a significant methodological approach in scientific research. Although it does not replace more detailed and rigorous review methods, it functions as a valuable tool for entering a field, mapping knowledge, and identifying new research directions. In other words, it is the first gateway to understanding the scientific reality of a subject, offering flexibility, comprehensiveness, and an expanded perspective.
